有m台不同的机器,n个不同的工件。每个工件有多道工序,每道工序由指定的机器在固定的时间内完成。一道工序一旦开始处理,就不能中断。每台机器一次只能处理一道工序。一个调度就是决定每台机器上工序的处理顺序,使得机器完成所有工件的时间最短。具体的,该问题就是要求在满足(1)、(2)两个约束条件的前提下,确定每台机器上工序的顺序,使加工的时间跨度(从开始加工到全部工件都加工完所需要的时间)达到最小。其中,(1)表示工件约束条件:对每个工件而言,机器对它的加工路线是事先确定的;(2)表示机器约束条件:对每台机器而言,一次只能对一道工序进行加工。()

Periodogram-powe
说明: 平均周期图法和平滑平均周期图法估计功率谱
从经典功率谱估计周期图法原理入手,从理论上分析了其存在的局限性,借助Welch算法对其进行修正。依靠Matlab强大的数值分析和信号处理能力进行实验!!
用周期图法和welch法分别估计了一下信号的功率谱密度。采样频率200Hz,时间序列长度2048,FFT数据点数2048。其中welch法使用hanning窗,窗口长度600.(Average periodogram and periodogram smoothing method to estimate the average power spectrum from the classical power spectrum estimation periodogram principle starting from the theoretical analysis of the limitations of its existence, with the Welch algorithm, amending them. Rely on the powerful Matlab numerical analysis and signal processing capabilities to experiment!! With periodogram and welch method were estimated signal power spectral density about. Sampling frequency of 200Hz, the time sequence length 2048, FFT data points 2048. Welch method which uses hanning window, the window length of 600.)

图像的平面微分平方和能够反映图像高频分
量的能量。用计算平面微分平方和的方法在空间域上计算相邻像素亮度差值的平方和,对应于在频率域上计算图像高频分量的能量和,此值越大,图像对焦越准确(Differential square image plane and the image can reflect the energy of high frequency. Computational method of Planar Differential squares calculated in the space domain to the square of the difference between the brightness of adjacent pixels and corresponds to the image in the frequency domain calculation of high frequency energy and, this value is larger, the more accurate the image focus)
